Nonparametric Neural Network Estimation of Lyapunov Exponents and a Direct Test for Chaos [PDF]
This paper derives the asymptotic distribution of the nonparametric neural network estimator of the Lyapunov exponent in a noisy system. Positivity of the Lyapunov exponent is an operational definition of chaos.

Advanced Science, EarlyView.In this study, we constructed a nanoparticle that was CD4 antibody‐mediated targeted, Fut7‐expressing plasmid‐loaded cationic liposome, namely CD4‐LDP‐Fut7. Upregulation of Fut7 expression in Tregs by using CD4‐LDP‐Fut7 can increase Treg homing to the intestine, thereby facilitating repair of the intestinal epithelial barrier and inhibiting ...

Bootstrap methods for inference in the Parks model
Economics: Journal Articles, 2020 This paper shows how to bootstrap hypothesis tests in the context of the Parks’s (1967) Feasible Generalized Least Squares estimator. It then demonstrates that the bootstrap outperforms FGLS(Parks)’s top competitor.

RUNX2 Activation in Fibro/Adipogenic Progenitors Promotes Muscle Fibrosis in Muscular Dystrophy
Advanced Science, EarlyView.This study revealed a novel role of the chemokine‐TGF‐β1‐RUNX2 axis in determining the fate of FAP differentiation and modulating muscle fibrosis in patients and mice with muscular dystrophies. ABSTRACT Clinical evidence indicates concurrent muscle inflammation and fibrosis in muscular dystrophies (MDs); however, the molecular mechanisms underlying ...

Nonparametric FBST for Validating Linear Models
Physical Sciences ForumIn Bayesian analysis, testing for linearity requires placing a prior to the entire space of potential regression functions. This poses a problem for many standard tests, as assigning positive prior probability to such a hypothesis is challenging.

Nonparametric pseudo-Lagrange multiplier stationarity testing [PDF]
The framework of stationarity testing is extended to allow a generic smooth trend function estimated nonparametrically. The asymptotic behavior of the pseudo-Lagrange Multiplier test is analyzed in this setting.

Advanced Science, EarlyView.Microbiota‐derived quinolinic acid is used as an alternative source of replenishing the intracellular NAD+ pool induced by SIRT3 deficiency to regulate intestinal epithelial cell and T cell function, which has implications for targeting intestinal epithelial cells as an approach to the treatment of immune‐associated diseases, including colorectal ...

Advanced Science, EarlyView.This study demonstrates that polyC‐RNA‐binding protein 1 (PCBP1) in ventral hippocampal astrocytes modulates depressive‐like behaviors by regulating glutathione peroxidase 4‐mediated ferroptosis and synaptic glutamatergic transmission. PCBP1 overexpression intervention in the chronic unpredictable mild stress model rescues behavioral deficits ...
